RADIAL-LY COMPRESSIBLE ELASTIC HOLDER FOR YARN PACKAGES Filed Feb. 17, 1955 I 3 Sheets-Sheet 2 RADIALLY COMPRESSIBLE ELASTIC HOLDER FOR YARN PACKAGES Gert Tigges, Wuppertal-Cronenberg, Germany, assignor of one-half to Max Edmund Korlf, Wuppertal-Barmen, Germany Application February 17, 1955, Serial No. 488,934 Claims priority, application Germany February 17, 1954 9 Claims. (Cl. 242-11811) The invention relates to a radially compressible holder for yarn packages, and more specifically to a holder suitable to support a package of yarn during wet and dry processing, e. g. during bleaching, dyeing, etc. The cylindrical surface of the holder of the invention is formed by the windings of a spring. The major portions of these windings are parallel to the axis of the holder and are held together so as to form a cylindrical support for a yarn package. Individual windings are axially offset relative to each other.

It is an object of the present invention to provide a holder for yarn packages in which the windings of the spring are held by fixed rings which in turn are supported by radially disposed arms mounted on an axially located tube, so that when several elastic holders wound with yarn are stacked on top of each other, the compression of the packages is limited by the fixed length of the axial tubes, and by means of the latter, the individual packages may be stacked on a spindle of conventional design which at its upper end may be equipped with means for fastening and compressing the stack of packages such as a nut.

It is another object of the present invention to provide at their bottom end the yarn holder with ring shaped end plates which are fastened to the axial tube by means of radial brackets, and when the holders are stacked on a spindle, these end plates serve to separate the packages.

It is still another object of the present invention to provide a preferred embodiment in which these end plates are designed in such manner as to serve as a means for introducing dye liquor or other processing liquid into the interior of the yarn package.

It is yet another object of the present invention to equip the end plate of the bottom yarn holder on each spindle on its underside with a female conical connector which registers with a corresponding male connector at the base of the spindle through which the processing liquid is introduced, thereby providing a liquid tight connection to be established between the stacked yarn packages and the source of process liquid simply by putting the bottom yarn holder in place, while the topmost yarn holder is covered with a cap which is held down by the nut on the central spindle.

With these and other objects in view which will become apparent in the following detailed description, the present invention will be clearly understood in connection with the accompanying drawings, in which:

Figure 1 is an elevation of the yarn holder;

Fig. 2 is a plan view thereof;

Fig. 3 is an axial section through two yarn holders, stacked on top of each other;

Fig. 4 is a plan view of a connector ring; and

Fig. 5 is a plan view of a modified end plate for a yarn holder.

Referring now to the drawings, the surface of the yarn holder is formed by the windings of a spring 1. These windings are of unequal lengths and offset relative to each nited. States Patent "ice other, and are held together so as to form a cylinder. Because of the offset positions of the windings of the spring 1, the front ends of the yarn holder show projections and depressions which engage each other when several holders are stacked, until the yarn packages or windings mounted on the holders engage each other, thus forming a continuous tight column. When a processing liquid such as a dye liquor is forced into the center of the holders under pressure it cannot flow out except by passing through the yarn packages.

The spring 1 is supported by two or several wire rings 2 which are mounted on radially disposed arms 3 supported on an axial tube 4. The bottom end of the yarn holder is equipped with an annular intermediate plate 5 which is connected to the axial tube 4 by radial arms 6.

i The yarn package rests on the intermediate plate 5. When several yarn packages are stacked as shown in Fig. 3, an intermediate plate is also located between the packages, thus separating them and providing a support for the yarn package mounted on the spring holder and thus preventing them from tangling.

When several yarn holders with their packages are stacked, the axial tubes 4 are slipped over a spindle 8 which is mounted on the dyeing machine. The topmost yarn holder is covered by an end plate with cap 9 which is pressed down by a nut 10 of the spindle 8. The packages 7 are compressed by means of the nut 10 and the spindle 8 until the tubes 4 of the yarn holders engage each other. The compression of the packages, therefore, is limited by the length of the tubes 4 and the bottom package of each stack cannot be compressed more than the top package so that dyeing or other treatment of the packages is completely uniform.

If it is desired to wind packages of greater width than the length of the axial tubes 4, spacer tubes (not shown) are placed between the individual tubes 4.

In order to provide simple means for connecting a stack of packages according to Fig. 3 to the supply of processing liquid, the underside of the end plate 5 of the bottom yarn holder is provided with a connector 11 with preferably conical female center opening which registers with a corresponding male connector 12 at the end of the line which supplies processing liquid. This connector also carries the spindle 8. Simply by placing the stack of packages on their holders on top of connector 12, a tight connection for the processing liquid is provided. The liquid enters the hollow core of the yarn packages and penetrates them from there.

The intermediate plates 5 of the spring yarn holders may be sheet metal rings of preferably corrugated construction to counteract any tendency towards channeling of the processing liquor. They may also be permeable to the processing liquor and may consist of several wire rings 13 as illustrated in Fig. 5.

While I have disclosed several embodiments of the present invention, it is to be understood that these embodiments are given by example only and not in a limiting sense, the scope of the present invention being determined by the objects and the claims.

I claim:

1. A radially compressible elastic holder for yarn packages for dry or wet processing comprising a spring having a plurality of windings, the outer portions of said windings defining a substantially cylindrical body adapted to receive the yarn windings and an axially disposed tube carrying a plurality of first radially disposed arms and a plurality of second radially disposed arms, a plurality of ring members secured to the outer ends of said first arms and passing through the windings of said spring in order to limit the expansion of said spring in radial direction, and at least one annular plate secured to said second arms,

said plate being adapted to engage one of the end faces of said yarn packages.

2. The holder, as set forth in claim 1, in which the windings of said spring are axially offset relative to each other, so that some of said windings project axially beyond said cylindrical body.

3. The holder, as set forth in claim 1, in which the windings of said spring are of unequal length, so that some of said windings project beyond said cylindrical body.

4. A radially compressible elastic holder for yarn packages for dry or wet processing comprising a plurality of springs, each having a plurality of windings, the outer portions of said windings defining a substantially cylindrical body adapted to receive the yarn windings and a plurality of axially disposed tubes in stacked up position and carrying a plurality of sets of first radially disposed arms and a plurality of sets of second radially disposed arms, a plurality of ring members each secured to the outer ends of said arms of one of said sets and passing through the windings of said springs in order to limit the expansion of said springs in radial direction, and a central spindle received by said tubes, and a plurality of annular plates, each secured to the outer ends of said second arms of one of said sets, said plates being adapted to receive one of said yarn packages between each pair of adjacent plates.

5. The holder, as set forth in claim 4, in which the distance of the said plates corresponds with the predetermined width of said yarn packages.

6. The holder, as set forth in claim 1, in which said annular plate is permeable.
